I searched for "int" in verilog-mode.el and followed verilog-declaration-core-re to verilog-declaration-re. Adding to verilog-declaration-re will probably do what you want; I'd add it via a new variable that gets merged into declaration-re. However note it will be global and needs to be correct before verilog-mode is compiled as these variables are defconst for speed, which is nasty.

Optimally, as you requested it would use verilog-typedef-regexp. However to do so properly, since verilog-typedef-regexp can be different per buffer (buffer-local) verilog-declaration-re and all of the variables downstream that are now constant need to be recomputed on each buffer and made buffer-local. That's very ugly. Instead it's probably better that those variables become defsubst's so they evaluate instead when used. I'm not sure how much slower this will make indentation.

Ditto adding it to verilog-font-lock-keywords, though that's at least a normal variable.

I think you see why this hasn't been done yet.

If you'd like to take a stab at this, and get something reasonably clean out, I'll take the patches back.

BTW verilog-typedef-regexp if used needs to be specified as "\w+_s\>" or similar, since it needs to match in the middle of a line instead of only against a string with one variable in it.

Ack. Doesn't look good. The first approach - having to set variables before gererating the .elc file doesn't seem like it would work. The 2nd approach, using verilog-typedef-regexp, is how it would need to work to be useful. It should be buffer local. I'm not up on defsubst, so I can't comment.

As for verilog-font-lock-keywords, I think it needs to be a separate variable/face just for user-defined types. I want to be able to tell LRM keywords from stuff I add.

I don't really have time or knowledge to work on this, but I'll probably try anyway :)

Hi Wilson.

I'm hitting this again and my elisp still isn't good enough to fix this correctly. However, I've hacked a solution for my own use. I've edited my local copy of verilog-mode.el to manually add the handful of user-defined types and it seems to work - at least for highlighting and indenting.

I added these lines in the middle of defconst verilog-declaration-core-re (around line 2750):

    ;; my types
    "uint_t" "wreal4state"

And these around 3180:

    (verilog-my-keywords
     (eval-when-compile
       (verilog-regexp-opt
        '("wreal4state" "uint_t") nil)))

And these in setq verilog-fint-lock-keywords around line 3270:

      (cons (concat "\\<\\(" verilog-my-keywords "\\)\\>")
            'font-lock-type-face)

It's a hack but pretty manageable - at least until it breaks something. Maybe this will give you an idea on a better version using a variable / regex in the Local Variables section.
